To a-ZZ {wlwm tammy concern:

Be` it .known that LJOHNC. JUNiriNsa citizen of the United States` residing at Minneapolis, in the` countylof Hennepiii4k ,and State lof Minnesota, have invented certain lnew yand usefullmprovementsin Grain Sep# arat'ors; and I vdo hereby declarethe,following to be al full, clear, and exact description ofthe invention, suchs as will enable others skilled inthe art to which lit appertains to make and use the same.

My invention relates to, grain separators or separating machines of the general. type disclosed and claimed inLetters lPatent ofV the United yStates #1,864,247, issued to C. W. Carter of date January, 1921, and also disclosed and claimed in application filed by said C. W. Carter as inventer 0f even date herewith and entitled @Grain separators.

The invention herein disclosed and claimed is in the nature of a modication of or iinprovement on the Carterseparators and provides certain highly important improvedA featiiresall of which lwill he hereinafter described or illustrated` and claims. t

In the accompanying drawings, which illustratev the invention, vlike characters indicate like parts throughout theseveral views. y

yhaving separating surfaces that y. would ceive certain kinds of grain or material and j plates havingpocketsthat would receive the' the same-side `of the'disk or'plate My invention is directed particularly vgrainor in aterial and -dis'chargethe saine1 at" disksV or plates, theseparating surfacesfof which are formed withperforations,,through which certainkinds ofV inaterial', such as 'p wheat, for examplawill freely` pass,.w;hile

IAs a highly iin-y portant feature of .this invention,l the i pery forated disks are arranged in pairs, ea'chg pair of disks affording what is designated'asfa disk unit. 1n this arrangement, the wheat or other materials passedl thronghfthe perforations -of the two disks f fromthe .opposite q vsides of the disk unit, willhe deliveredinto the spa-ce between `the ltwoj'disks and, from such space,".the selected materialffwi'llfhe picked up orotherwise discharged `so`as` to maintain the separation thus accomplished.

Of course, Vthisseparatf'i-r is capable ofuse 'A y for separating various different kinds vof grainssor seeds orf other materials, but' Lit will Yfirst he ldescribed las designed andfnsed,for.

the separation f wheat from oatsand 'liandling cominingl'edfgraiiis frequently `Vdesig? nate'd as suocotash4 As a suitable i container for such material,

I provide ay horizontally ldisposed ydruindike casing 12, which may'loeconyeniently ,supf y ported` hy legsl'. 'A't'oi near [its receiving end, the casing, 12 is'providedfwitli. an inlet .0r 'supply hopiierls' equippedntsbottm with -feed-CQntrollns!means 'sich a'sride pendently niovahlegates' .i the,delivery,

yone end, is shown as provided with a pulley 2l for rotating the saine through a powerdriven belt not shown. 'llhis'shaft 20 carries a multiplicity of sets of radial arms in the form of obliquely set propelling blades 22, each set being, as shown, rigidly connected to an annular rim 23. 1 l

rlhe disks 24E, which belong to or make up the same disk unit, are, at theirinner edges,

riveted or otherwise rigidly secured to the respective rims 28 and are concentrically located in respect to the shaft 20. Thus, the

Vtwo disks of the units are spaced to aord annulary chambers 25 between them. rlhese disks are formed with perforations 26,

f'vvhich, for the separation of wheat from oats, should be large enough `to permit wheat v'tol pass freely therethrough when subjected to slightlpressure, such as produced against 'the faces of the disks as they are moved through vthe body or mass of commingled 'grain or succotash ,i/. .The numeral 27, Figs. l, 3 and 4, indicates yagitating cleats or strips secured on the faces or' the disks 24, and the numeral 28,

Figs. y3, el and 5,. indicates collecting cups or pockets secured to the inner faces of the unit-forming disks near the peripheries thereof. lln'Figs. l, 3 and a, the numeral 29 'indicates pliable joint strips applied to the interior of the easing 12 and against which the peripheral edges ofthe disks are arranged to run to thereby prevent the wheat,'which enters the chambers 25, from escaping bac-k into the mass of commingled grain. ln the drawings, the agitating cleats 27 are exaggerated in transverse width and probably are shown in greater number than would be actually required.

The construction so far specifically dei scribed is that illustrated in Figs. l to 5, in-

mingled stock `rsively fed bythe blades 22 through the openelusive,v and the operation thereof, when de"k signed for use in separation of wheat from oats, is substantially` as follows:

v The disks will be rotated in clockwise direction in respect to Figs. 3 and 5, and under such rotation, the upper portion of the comwill be slowly but progresings in the disks in a direction from thereceiving toward the Ydelivery end of the casing, and the oats will finally be discharged Leases? through the passage 16 and spoutl. k'lhe oats, under rotation of the disks, willnat- Vurall beturned atwise against the disks and, being too long to pass laterally through the perfoi'ations 26 thereof,r will be rejected by the disks, while the wheat will pass quite freely through the periorations and into the chambers or spaces 25 between the disks ofY the several disk units. The goodwheatthus collected in said chambers or spaces 25 will be' picked up by the pockets or cups 28 and carried upward and over and discharged into the collecting hopper i8 and discharged through the spout i9. rllhe oats will be progressively moved onward and finally discharged. s stated, through the lli.

'-.lus the nai-ation of' wheat and cats is .ly omp'iished. Uf course, by prov ig *i e d.` las with the proper sized permachine. sere, the casing l2 is provided with a plurality,as shown three, longitudi-- nally spaced collecting hoppers 18a, 18h and 18C, and thek disk units are correspondingly arranged in three` groups, a, o and c. These disk units are lor may be of the same construction as already described', but the group c' will deliver to the hopper itl, the group tl will deliver to the hopper 18", and the group c will deliver to the hopper 1.8. Jalso, the disks 24% of group i have perforations 2G, not large enough to pass wheat or large seeds, but only large enough to pass small seed; the disks of group Zi have peritorations 26h, not large enough to pass wheat, but large enough to pass quite large seeds; vand the disks of group c have perforations 2GC 4large enough to pass lwheat but not large enough 'to pass oats or barley laterally therethrough. With this arrangement, small seeds will be delivered into the hopper lila,

largeseeds or broken wheat, for example,

will be delivered into the hopper 18h, good wheat and the oats will be discharged from the spout li'.
